12 Claims. (Cl. 20-53) This invention relates to window structures, andparticularly to a tier of windows, preferably of the type used in theSouth. They are the so-called awning type WlH- dow and include themechanism for operating the same.

Among the objects of the present invention is to provide in the abovetype of window construction a novel type of hinge mechanism by which thewindow sashes may be swung about horizontal pivots and wherein the hingeconstruction is formed so that the metal of the hinge will embrace thevertical side members of the window sashes on opposite ends of the sashin a manner so that the stresses and strains are not placed upon thefastening screws that fasten the hinge members to the sash framemembers.

Another object of the invention is to provide a combined hinge partmember and window sash operating arm, all in one piece, therebyproviding a more economical and rugged structure for accomplishing thetwo functions.

Yet another object of the invention resides in the provision of a hingestructure for pivotally mounting the upper ends of the window sash tothe vertical s1de members of the enclosing window frame in such a mannerthat the upper sash may be adjustably slid downwardly with respect tothe stationary portion of its hinge to permit an operator to reachoutwardly above the top of the downwardly adjusted sash for cleaningpurposes.

Another object of the invention resides in providing a hinge member fora window wherein the hinge members are vertically adjustable withrespect to one another in one position but are locked from such verticaladjustment in another position.

Another object of the invention is to provide a hinge for a windowconstruction which not only permits one of the members of the hinge toswing upwardly and downwardly about a horizontal axis but also in anadjusted position permits said hinge member to shift bodily upwardly anddownwardly with respect to its complementary hinge section to permitcleaning of the window sash.

Yet another object of the invention resides in the provision of aWeatherstripping for sealing the joint between the upper horizontalframe member of the window sash and the adjacent stationary horizontalupper window frame member so that during the opening and closingmovements of the window sash as the window swings about horizontalpivots, the junction is completely sealed at all times so as to preventthe ingress or the spattering in of rain and the like.

Another object of the invention resides in the provision ofWeatherstripping, preferably metallic Weatherstripping, to seal thevertical sides of the enclosing window frame and the several verticallydisposed window frames of the tier of awning-like window sashes.

Another object of the invention resides in providing a Weatherstrippingconstruction for sealing the bottom of the top surface of the sill andthe lower horizontal frame member of the lowermost frame member of thewindow sashes of the tier of window sashes.

Yet another object of the invention resides in the provision of flexiblepads, preferably of felt, for insertion between the copper or othermetal or flexible weatherstripping and the stationary frame member towhich they are attached, whereby to maintain the resiliency of theWeatherstripping and/or also to assist in the sealing action.

Another object of the invention resides in the pro- 2 vision of thenovel type of connection from the operating shaft that raises and lowersthe tiers of window sashes and the crank handle on the inside of thewindow stool.

Another object of the invention resides in the provision of variousimprovements in the extension shaft and the manner in which its innerend is adjustably mounted with respect to tile stools or to elevatedstiles located well above the floor and for connection to an elongatedcrank member.

Yet another object of the invention is to provide means for preventingthe over-swinging of the crank arm for actuating the raising andlowering linkage mechanism for the sash arms.

These and other objects of the invention will be ap-' parent from aperusal of the following specification, when taken in connection withthe accompanying drawings, wherein:

Referring now to Figure 1, there is shown in perspective view a portionof a building having a window structure embodying the present invention.This window structure 1s conveniently called an awning type window,since the window is provided with a plurality of sashes 11 and 12 and 13arranged in vertical series, one above the other, so that when closedthe upper sash rail and the lower sash rail of ad acent sashes are inabutment, thus limiting the need for any mullions or other spacing barsbetween the sashes of adjacent windows. Figure 1 shows a window assemblyhaving a single vertical tier of sashes which when opened in awningfashion appear as shown and have the advantage of permitting adequateair circulation since the awning effect deflects the air upwardly, thusconstantly moving the warm air normally accumulating at the ceiling asin cases of other types of window constructions.

Each of the sashes 11, 12 and 13 is hingedly secured adjacent the topsash rail to the outer window casing, and in the present invention asuitable operating mechanism sectional view taken on the lineperspective view of the weather- 3 is mountedon-the inside of the windoweasing between the side jambs and between the window and the window sillso as to eliminate the need of expensive structures which would berequired where the operating member :is fmounted within .the verticalside members or stiles. .Thiszmanner of structure permits a window ofthis type to be'inserted in the ordinary window opening.

:Referring now to Figures 2, 3, 4'and 5, it will be'seen that theupper'window sash 11.is hingedly supported by a pair of hinges,generally designated by the numeral 19, .which servetohinge eachuppermostfsashto the side jambs of the window frame, as hereinafter setforth. This hinge construction .and:the manner:in which it is mounted.on the window. sash and side jambs of the stationary frame ofthewindow'constitute-one'of the novel features of the present invention.

Inasmuchas the nomenclature of the many components of theWindow1construction and frame construction are importanbtoadescription'of' the invention and description of the hinge, it isthought appropriate first to describe the various component 'parts ofthe sashes and the window .frame members :in which the sashes aremounted. The sashes 11 to 13 are supported within a structure comprisinga head jamb 21,"see Figures 4and 5, which may :beErabbeted at .22 tofacilitate mounting a screen window without the use of special hardware.The frame also includes a sill 23 and interconnecting side jambs andside stops. Immediately above the upper sash rail of the window sash 711 there ispositioned a combined-head blind and head jamb 24b. This is ahorizontally extending member and the upper sash member of the upperwindow 11 is arranged to abut this head blind 24b in weathertight,water-tight arrangement when the window is in closed position, as shownin Figure '4. This arrangement likewise permits the upper sash to be-pivotally swung outwardly as shown in Figure 16, away from this headblind 24b, while maintaining a waterproof and weatherproof seal ashereinafter disclosed.

The sill 23 is mounted in interlocked relation to a stiffener 26:againstwhich is positioned a window stool 27 and the usual window apron28, seeFigure 2.

The upper head jamb 21, see Figure 4-, is preferably recessed, atopposite ends, sufiiciently to receive the upper portions of sash arms29. The construction of each of .these sash arms as an integral part ofone of the hinge members of the sashes is one ofthe features of thisinvention. This integral hinge and sash arm is shown in detail in Figure13, see also Figure 17. In general it comprises a single stampedmetallic blank comprising an intermediate flat plate-like portion 29awhich is bent at right angles to provide a normally disposed second fiatplate portion 29b provided with one or more attachment holes, as shown.The plate-like portion 2912 has integrally joined thereto a thirdplate-like portion 290 which is formed with an upward extensionproviding the sash arm generally designated by the numeral 29 having asuitable perforation 290. The opposite side of the plate-like portion29a is provided with an integral offset portion 29d in turn terminatingin a longitudinally extending, elongated, narrow plate-like portion 29c,the upper end of which is provided with a boss 29 formed with a per--foration 29g. In addition, the central plate-like portion 29a isprovided with a struckout tab 2% having a perforation 29:. Tab 2% liessubstantially parallel to and spaced from extension 29b. Thus there isformed a single piece of stamped sheet metal having the foregoing shapeand functional features now to be described.

This plate-like portion 29a as shown in Figure 17 embraces the outerside of the vertical frame member of the sash. Each window sash, such assash 11, is provided with a wooden frame comprising the vertical windowframe members 11a on opposite sides, and the top and bottom framemembers 11b. These frame members receive the glass sash pane, as is wellknown in the art.

In a similar manner the sashes 12 and 13 comprise the c vertical sashframe members 12a and 13a and the horizontal or upper and lower sashframe members 12b and 13b. Figure 17 shows the manner in which thecombined hinge and sash arm embraces each of the vertical mem bers 11aor 12a or 13a of the respective sashes 11, 12 and 13. Referring toFigure 17, the plate-like portion 29a is shown as lying in flat contactwith one of the two outer side walls Ila-a of the vertical frame member11:: of the window sash. The other plate-like portion 29b (see Fig. 13also) lies in contact with the inner face 11b b of-the vertical framemember 110 andis fastened thereto by a screw as shown, and the portion29c extends at right angles therefrom and upwardly, to form the sashbracket 29 as shown in Figure 17. On the opposite side of the plate-likeportion 29a the struckout ear 29h engages the outer face 11c-c of theframe member 11a and is fastened thereto by a screw, as shown.

In addition, the integral elongated plate-like member 296, see Fig. 13,extends vertically upwardly parallel with the central 'plate-like'member29a but is bent forwardly out of'the plane of the same. This portion,being perforated at 29g, forms a horizontal bearing for a pivot pin 29g,whereby thesashthrough the instrumentality of this pivotal hingeconnection on each side may swing about the horizontal axis of thisipivotpin 29g for raising and lowering movement. For the upper sashes ofeach series the complemental hinge members are different from thecomplemental hinge members of the lower sashes and this forms anadditional importantpart'of the invention. Thus, for instance, referringto Figures 12 to 15 inclusive, each complemental hinge 'member for theupper sashes comprises a stationary channel-shaped sheet metal blank-29j, see Fig. 13, having an integral rightangle plate-like portion 29kand an opposed andparallel plate-like portion 291 which forms aguideway. The plate-like portion 29k is provided with fastening openings29m by which this portion is fastened to one of the parallel, frontvertical members 24a of the window frame on each side thereof, see Fig.'12. The central plate of this supplemental hinge Iplate (see Fig. 13)is provided with an elongated slot .2911 which receives a pin 290, seeFigs. 14 and 15, on a vertical narrow bar 29p. The upper portion of thisbar supports the pivot pin 29g hereinbefore described.

As shown in Figure 14, the pivot pin 29g comprises a headed'shankportion 292 and a shoulder portion 29s and a reduced neck portion 29tand a riveted head 2911. The riveted'portion 291: fastens'the pin to thebar 29p and the shoulder portion 29s forms a bearing surface against theslotted member 29 see Fig. 13. A fiber washer 291' is interposed betweenthe surface of the bracket plate 29 and the inner surface of the portion292 of the hinge. This fiber washer 29r permits a loose fittingconstruction so that the lower portion of the bar 29p may be movedlaterally away from the slot to disengage the pin 290 from the slot asshown in dotted lines in Figure 14 and full lines in Figure 15.

The release of the pm 290 from the bracket 29k permits the hinge pin 29gto move downwardly in the slot 29n, thereby permitting the upper sash tomove downwardly the'length of the slot as the sash is swung outwardlyabout the pivot pin 29g. The upper sash thus assumes the loweredpositionshown in Figure 12 so that a window washer may insert '-his handover the top of the sash to clean the outside surface'of-the sash'panefrom the inside of the room and thus eliminate the need for any specialbrushes and equipment to clean the outside of the upper window sash.Whenthe cleaning is completedthe sashes with the-hinge members areraised until the pin 290 has assumed a position opposite the slot whenthe bar 29p causes the pin 290 to snap back into the slot 29a. in

other words, the pin 290 will ride over the lower edge portion 29w ofthe slot and will'snap into position above that edge 29w. Figure 14shows the pin 290 in position above the edge 29w to'lock the bar 29pto'thestationary hinge member-29 and thereby holdthe associated hinge pinof the upper sash in its uppermost position.

With respect to the lower sas'hes'it is not necessary to have the samedrop down to clean the outside of them because each one of these sashescan be reached from above when the next upper sash is in 'open position.Therefore the complemental hinge members for the lower sashes, eachcomprises a plate 79 having a right angle portion 83'provided with aperforated ear for the reception of a pivot pin 79a having anintermediate shoulder 79b and a reduced portion 790, see Fig. 20. Inaddition, there is a fiber washer 79d interposed between the fixedmember of the hinge on the side frame of the window and the movablehinge member which is attached to the sash,jallshown in disassembled'view in Figure 20. It is understood "that the member 79 of this hingeis attached to the front face-of the vertical member 2411 of the windowframe. These hinge connections are on opposite sides of each sash.

The various sash arms 29, which are attached to the various windowsashes 11 to 13, are interconnected by vertical link members 31. Theselink members are round rods flattened at their ends, the flattened endportions being perforated to receive pivot pins 31a which connect thelink members to the upper sash arms 29. The upper rods 31, on oppositesides of the window, are connected to the upper sash arms 29 in themanner illustrated in Figure 4 and at each its opposite or lower end isconnected to the adjacent, lower link member 31 by means of a pivot pin31a that passes through the opening 29c in the associated sash arm 29.The bottom end of such lower rod 31 is connected to the top end of thenext lower rod 31 and to the next lower sash arm 29 also by means of apivot pin 31a.

Finally, the bottom end of the lowermost link rod 31 is attached bymeans of a pivotal pin 31b, Figure 5, to a crank arm 34. By suitableplates 32, secured by screws passing through the side frame 24a, thereis supported a rock shaft 33 which carries at each end one of thesecrank arms 34. The rock shaft 33 is provided at one end with a gear 36which meshes with a worm gear 37 mounted on a shaft 38. This shaft 38has at its right hand end, as shown in Figure 4, a socket to accommodatea hexagonal extension which extends beyond the structure of the windowand has at its end a crank 39, see Fig. 2. Thus by rotating the crankthrough the before described connections the window sashes are raisedand lowered, the bottom portion of each window sash closing upon the toprail of the next lower sash. In addition, a plate 32a, Figures 4, and21, is fixed to the supporting plate 32 and is provided with a notch 32bwhich limits the movement of the gear 36 by means of a pin 36a fixed onthe outer face of the gear 36. The pin 36:: enters the slot 32b tocontact the back wall 320 of the slot and prevent the gear 36 fromrevolving more than a predetermined angular extent in a clockwisedirection. This is to prevent the turning of the crank 39 beyond apredetermined point in the window opening operation so as not to jam thesashes into the frame, thereby causing undue stress upon the hinges andother parts of the mechanism.

It will thus be seen that the operating mechanism is readily accessiblefrom the inside of the building and yet is hidden to a considerabledegree by means of an inside window screen 41, the upper rail of whichfits into the plowed or rabbeted recess 22 of the head jamb. The headjamb 21 is provided with a cut out portion 21a, shown in Figure 4 toaccommodate the upper portion of the hinge member 29 when the sash is inclosed position. This cut out portion 21a is closed at the top toprevent any dirt or dust from entering into the structure by this means.The bottom of the screen 41 rests upon the stiffener 26 which isretained by the window stool 27. The side members of the screen 41engage side stops 55 shown in Figure 6.

Weatherstripping means is provided for preventing the ingress ofmoisture and rain and wind when the sashes are in open position and alsowhen they are in closed position. A head strip 44, Figures 2, 4, 11, 12and 16, is attached to the upper window frame member 2412. This headstrip holds in place and is provided with a downwardly projecting copperWeatherstripping member 44a. This Weatherstripping projects downwardlywell below the upper surface of the upper window sash frame member 11b.The lower end of this copper weatherstripping is, of course, flexibleand flexibly engages the outer face of this upper window frame member11b of the sash whereby when the sash is in the closed position shown inFigure 4 or when it is in the open position shown in Figure 16 itoverlaps and contactingly seals against this flexible upper sash rail ormember 11!). This copper strip extends the entire width of the uppersash and thus forms an effective seal so that, as shown in Figure 16, ifheavy rains strike the upper frame and tend to splash, it will bestopped effectively so that it cannot enter into the room above the openupper sash 11 even when the sashes are in open position. There is nonecessity for any such Weatherstripping on the lower sashes because eachsash prevents the rain from entering below it.

In addition, side Weatherstripping members are provided, see Figures 6and 18, to make a weathertight seal when the sashes are closed. Theseside copper Weatherstripping members 4417 are hold by means of -of thehinge.

tacks or other fasteners to the side jambs 55 shown in Figure 6 and theyproject beyond the inner walls of these side jambs and beyond thevertical frame members 24a to engage the rear faces of the window sashmembers 121: and 12a.

In addition, Weatherstripping is provided for the top of each of thosesashes 12 and 13 which are below the upper window sash 11. To this end,aflixed to the upper horizontal window sash members 1212 and 13b ofsashes 12 and 13 are horizontal elongated copper strips 44c, Figures 4and 18, that are attached as at 44d. Felt pads 44e are provided in thecorners and underlie the extreme ends of this Weatherstripping in orderto give it resiliency and prevent it from being bent or collapsed flatonto the upper wall of the sash members 12b and 13b of the sashes 12 and13. These felt pads project outwardly beyond the free resilient edge ofthe strip and engage the vertical weatherstrips 44b whereby to provideseals at these points.

An additional copper or other flexible Weatherstrip 44;, Figure 16, isatfixed to the underside of the head piece 24b and at each end it isprovided with an underlying, resilient pad (not shown) similar to thepad 44c, which projects therebeyond to engage the side Walls of thevertical window frames and also to engage the top ends of the verticalweatherstrips to provide similar sealing functions and to prevent theupper horizontal Weatherstripping members 44 from being packed downtightly when the Windows are closed from time to time.

In addition, a lowermost copper sealing strip 44h, Figure 4, is attachedto the sill as at 441' and runs the length of the sill. The free end ofthis strip extends normally upwardly and resiliently engages the lowerside of the frame member 13b throughout its length, each one thusforming a seal at this point for the lower window sash when in closedposition.

If desired, a storm sash complete Window pane can be substituted for thescreen 41 and mounted in the same manner as the screen itself, as shown.

Figure 7 shows a modified form of stool detail for tile construction. Inusing this tile stool construction means must be provided foraccommodating the operating handle for the windows to the width of thetile stool construction. To this end therefore the end of the shaft 38is provided with an extension thimble 381) that has a socket toaccommodate a crank handle 39. This crank handle 39 extends through anadjustable sleeve connection consisting of the plate 38c afiixed to thewindow stool stiffener 26 by screws 2%. The plate 38c carries anexternally threaded sleeve 38d which threadedly engages an outer sleevemember 38:2 fastened to a plate 38 which in turn is perforated to fastento the inside wall below the stool and into a wooden frame member 38g.By turning the plate 33 and threadedly moving it back and forth on thethreaded sleeve 38d, an adjustable position can be arrived at at whichthe plate 38 may finally be attached to the frame member 38g and held inpermanently aflixed position.

Figure 9 shows a construction wherein the crank operating means ispositioned at an upper elevation well above the floor so that it cannotbe reached by the hand. In this case the outer end of the extensionshaft is mounted in a substantially U-shaped bracket 38m which supportsa pair of bevel gears 38n and 380, the gear 38mv being connected to aconnecting sleeve 38;) by set screw 38g. This interconnecting sleevealso connects with the elongated extension shaft 40. The bevel gear 380has attached to its stub shaft a ring member 381' for engagement with ahook 38s on an extension rod or crank handle 381, see Fig. 10. Thiscrank handle may be of considerable length for operating the windowsHvhcn the same are at a considerable elevation above the oor.

As shown in Figures 6, 11 and 12, a preferably rounded head thumb tack50 is inserted into the inner opposed walls of the vertical window framemembers 24a to be engaged by the adjacent face of the plate-like portion29a of the movable hinge member, as shown particularly in Figure 17, soas to permit accurate spacing between these two surfaces during theopening and closing movements of the window and also to form a smoothsurface bearing against the movable portion 290 It is understood thatthese thumb tacks are on each side of the Window sash and operate asabove described. As shown in Figure 12, to permit the lowering of the.upper sash for cleaning purposes, the pivot connectionso'f the upperrods 31 to the upper sash arms 29 must be released. This 'may beaccomplished by first removing the snap fasteners 31d from the pins 31aat the upper rods 31, one only of these snap fasteners 31d being shownin Fig. 12. The snap fastener 31!! is removed from its associated pin31a by operating it out of an annular groove 31s in which it ispositioned when attaching the rod 31 to the associated sash arm 29.After the snap fasteners 31d have been removed, the pins 290 are removedfrom'the slots in the stationary hinge members 29 It will thus be seenthat the hinge member is constructed in a manner such that the movablehinge memher is enabled to support the vertical side frames of thewindow sashes on opposite sides thereof, with a sort of clamping actionsince the spaced walls of this hinge member engage opposite sides of thevertical sash frame 11a, as shown in Figure 17, the screws shown merelyserving to hold the hinge member in place instead of supporting theentire hinge. Furthermore, it must be evident that by forming themovable hinge member and sash arm in one piece considerable economy andruggedness of structure are provided.

In addition, the construction of the upper hinge provides a very simplemanner of permitting the upper sash pane to be cleaned from the inside,without the use of special brushes.

By reason of the manner of arranging the Weatherstripping, moisture andrain are prevented from entering the window through the various joints,also making the entire structure adaptable to climates where the weatheris more severe.

It is apparent that many widely different embodiments of this inventionmay be made without departing from the spirit and scope thereof, andtherefore it is not intended to be limited except as indicated in theappended claims.
